RACK ADJUSTMENT FOR LOOMS.

Specification of Letters Patent.

Patented Feb. 15, 1910.

Application filed May 13, 1909. Serial No. 495,699.

To all whom it may concern:

Be it known that I, SOLOMON KENDRICK, a citizen of the United States,residing at Rochester, in the county of Monroe and State of New York,have invented certain new and useful Improvements in Rack Adjustment forLooms; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable othersskilled in theart to which it appertains to make and use the same.

This invention relates to improvements in rack adjustment for looms.

The object of the invention is to provide means whereby the rack bed ofnarrow fabric looms may be adjusted to compensate for the wearing of theparts, thereby keeping the rack bed up in proper position with therelation to the shuttle block.

`With this and other objects in view, the invention consists of certainnovel features of construction, combination and arrangement of parts, aswill be more fully described and particularly pointed out in theappended claims.

In the accompanying drawings: Figure. 1 is a vertical sectional Viewthrough a portion of a loom showing the application of the inventionthereto. Fig. 2 is a. rear view of the same parts. Fig. 3 is a detailview of one of the adjusting plates.

Referring more particularly to the drawings, 1 denotes the batten of aloom, 2 denotes the shuttle block, 3 the pinion, 4 the rack, 5 the rackbed, 6 the false bottom arranged below the rack bed, and 7 denotes theshuttle. These parts may be of the usual or any desired construction anddo not form a part of the present invention.

In carrying out the invention, I provide the hatten 1 with a series ofvertically disposed passages 8, which communicate at their lower endswith right-angularly formed rearwardly extending passages 9, which openthrough the rear side of the batten, as shown. In the right-angularlyformed portions 9 of the passages are arranged interiorly threadedsockets 10, having enlarged outer portions 11, and attaching flanges 12,which engage the rear sides of the batten and are screwed or otherwisesecured thereto. In the threaded sockets 10 are adjusting screws 13,having pointed or conical shape inner ends 14, and heads 14 which lie inthe enlarged portions 11 of the sockets.

The upper portions 8 of the passages in the hatten communicate at theirupper ends with the channel 15, in the upper side of the hatten whichforms the seat for the rack bed and false bottom. In the channel 15,below the false bottom 6 is arranged a series of adjusting plates 16,which are provided on their under side and midway between their endswith outwardly extending shanks 17, the lower ends of which are beveledat an incline as shown at 1S. `When the adjusting plates are inoperative position, the beveled lower ends 18 of the shanks 17 are inposition to be engaged by the conical inner ends of the adjusting screws13, whereby when said screws are turned inwardly the conical endsthereof will raise the adjusting plates 16, thereby elevating thatportion of the false bottom engaged by the plate and through the sameelevating or holding the rack bed up in proper position, thuscompensating for the wear of the false bottom or other working partsengaged thereby.

In the form of looms now in use, when the rack bed drops below theshuttle block by reason of the wearing away of the false bottom thepinion will strike the top of the rack teeth which will sooner or latercause the breaking of these parts. As now constructed, when the rack barhas thus lowered to a dangerous position, it is necessary to remove theshuttle and blocks from the batten and replace the worn false bottom bya new one, after which the shuttles and blocks have to again be put inplace, and it is only a short time before this operation has to beperformed again. By means of my improved adjusted mechanism, this laborand expense is overcome and the parts properly adjusted without removingany of the same.

In wearing away, the false bottom, almost invariably wears first in oneplace more than another so that the rack bar is thrown out of alinementat one end or the other, or intermediate its ends. By providing aplurality of adjusting plates arranged as herein shown and described,the false bottom may be adjusted at such points where the same hasbecome worn, thus elevating the rack bed at this point and keeping thesame in perfect alinement.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention as defined in theappended claims.

Having thus described my invention what I claim is:

l. In combination with the false bottom, a shuttle operating mechanismof a loom, a series of adjusting plates arranged below said bottom,shanks formed on said plates, said shanks having beveled lower ends, aseries of adjusting screws arranged at right angles with the shanks ofthe adjusting plates and having conically shaped inner ends adapted toengage the beveled ends ot' said shanks, whereby the latter and saidadjusting plates are elevated to adjust said false bottom.

2. In a loom ot' the character described, a batten having formed thereina channel and a series of right-angular passages communicating with saidchannel, a false bottom arranged in said channel below the shuttleoperating mechanism of the loom, a series oitl adjusting plates arrangedbelow said false bottom, shanks arranged on said plates and projectinginto one portion of the apertures in said batten, said shanks havingbeveled lower ends, threaded sockets arranged in the other portions ofsaid right angular passages, and adjusting screws Vin said. sockets,said screws having conical inner ends to engage the beveled lower endsof said shanks, whereby said adjusting plates are actuated to adjustsaid false bottom.

3. In a loom of the class described, a batten having formed therein achannel and a series of right angular passages connected with saidchannel, a false bottom arranged below the shuttle operating mechanismof the loom, a series of adjusting plates arranged on said false bottom,shanks extending' from said plates into the vertical portions of saidpassages in said batten, said shanks having beveled lower ends andadjusting screws screwing through the lateral portions of said passagesagainst the beveled ends of said shanks to adjust the adjusting plates.

in testimony whereof I have hereunto set my hand in presence ot twosubscribing witnesses.

SOLOMON KENDRICK.
